LANTERN-TOP.

Specification of Letters Patent.

Application filed July 21, 1905.

Patented July 20, 1909.

Serial No. 270,637.

To all whom it may concern:

Be it known that I, DAVID C. KLINE, a citizen of the United States, and resident of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Lantern- Tops, of which. the following is a specification.

This invention relates to lantern tops, and consists in the mechanism hereinafter described and claimed.

In the drawings :Figure 1 is a vertical section on the line 11 of Fig. 2 of a complete lantern top embodylng th1s inventlon;

Fig. 2 is a plan view of the same lantern top having the upper canopy removed; and. Figs. 3 and 4 are views of other forms of the same invention taken through lantern tops on the same vertical section line as Fig. 1.

To a suitable portion of the frame of a lantern, such. as to the upper ends of the air tubes 1, 1, is fastened a collar 2, preferably having the lower deflecting flange 3 and the perforated guide plate 4. The top 5 of the collar 2 is turned inward, and forms a guide for an inner or globe-holding tube 6, which is adapted to slide within the collar 2, which is guided also by the perforated guide plate 4. The collar 2 has therefore apertures at its top 5 and at its bottom 4. A spring 7 is adapted to force the globe-holding tube 6 downward with reference to the collar 2. This spring may be a coiled spring, and may have one end engaged under the upper closed. end 5 of the collar 2, and the other end may engage the globe-holding tube 6. The coiled spring therefore lies in the air space 8 between the collar 2 and the globeholding tube 6. The air tubes 1, 1 not only support the collar 2, but also make connection through it with the air space 8. Apertures are made through the walls of the globe-holding tube 6 through which air may pass from the space 8 either in or out of the tube 6, as the case may be. For this purpose, a portion of said tube 6 is stamped and pressed inward from the tube itself, forming an aperture therethrough and a deflecting plate. In the present case it is deemed preferable to employ two such deflecting p ates 9, which do not register with the openings (shown in dotted lines in Fig. 1) through the collar 2, whereby air from the side tubes 1, 1 passes into the interior of the collar.

In Fig. 1 the deflecting plates 9 are connected to the tube 6 at their upper ends, and extend inward into the interior of said tube and downwardly. In Fig. 3 the deflecting plates 10 are connected to the tube 6 at their lower ends, and extend inwardly and upwardly therefrom. In Fig. 4 the said deflecting plates are connected to the tube 6 at their middles, and have each the inward and downwardly directed portions 11, and the inward and upwardly directed portions 12, in this case forming double deflecting plates.

At the top of the globe holding tube 6, openings 13 are provided for the escape of the heated products of combustion, and upon stems or standards 14: upon the upper edge of said globe holding tube 6 is fastened the top or canopy 15, which may be provided with a ring 16.

What I claim is 1. In a lantern top, air tubes, a collar fastened to the ends of said air tubes and having an inwardly turned flange for its top and a erforated guide plate for its bottom, a globe olding tube movable in said collar and guided by said flange and by said guide late, and having apertures through the wa ls of said tube substantially equidistant from the ends of the air tubes, and a deflecting plate opposite each a erture of substantially the same area as sait aperture and projecting inward from said globe holding tube, and a spring outside said tube for pressing it downward with relation to the collar.

2. In a lantern to air tubes, a collar fastened to the ends of said air tubes and having an inwardly turned flange for its top and a perforated guide plate for its bottom, a globe holding tube movable in said collar and guided by said flange and by said guide plate and havin apertures through the walls of said tube substantially equidistant from the ends of the air tubes, and deflecting plates formed from the globe holding tube itself and projecting inward therefrom and thereby formin apertures opposite which the deflecting plates are held, and a spring outside said tube for ressing it downward with relation to the co lar.
